When you try to install VMware Workstation on a computer with Hyper-V installed, you get this error:

VMware Workstation

Error: This product may not be installed on a computer that has Microsoft HyperV installed.

To install VMware Workstation on a computer with Hyper-V installed, uninstall the Hyper-V role (Add / Remove Windows Features), then install VMware Workstation, then reinstall the Hyper-V role.

If you are currently using Hyper-V VMs, you may need to point Hyper-V to the location of these after you reinstall.

❗ Note: There are reports that you can only run x32 bit VMs in VMware Workstation on a computer with Hyper-V installed.

❗ Update: I’ve now tried this myself and found that it doesn’t work. It seems that there is no way to make VMware Workstation work on the same computer as Hyper-V (running simultaneously, anyway). After installing both Hyper-V and VMware Workstation on the same computer, you get this error when you try to start VMware Workstation VMs:

VMware Workstation

VMware Workstation and Hyper-V are not compatible. Remove the Hyper-V role from the system before running VMware Workstation.
